Cannot SAVE Profile Name Change (or upload profile pic)

I have been on support chat all morning and have been sent around many times. The support team keeps telling me my name is correct, etc. They don't seem to be able to distinguish between account name and profile name. When they can, they send me to a link to Profile change. It's pretty straight forward: click on change button. Change. Save.

but.....

I cannot save.

Message comes up as red box with warning sign saying: cannot save, try again.

Can someone help me?

Mac. Mojave. I have Adobe cc-all products.
